Hello All, I own a "89 New Yorker with ABS and rear disc brakes. On Friday, the rear brakes they began to grind. So, I immediately parked it until I was able to get parts. Today, after gathering new pads and a loaner rear disc brake tool, I had planned on tackling the job. Unfortauntely, all I was abe to do is remove the rear caliper and pads. I could not get the tool between the caliper piston and edge to rotate the piston back in. I believe the piston is at its full outward travel. I tried using the tool (a spanner disk with a clamp) but the piston was too hard to move. Anyone have any ideas? BTW, Anyone know what type of ABS system is on this puppy? Thank you, Jesse
